Gearing for windmills



Q STATES MILTON KEYS, OF FORT WORTH, TEXAS.

GEARING. FOR WINDMILLS.

SPECIICATION forming part of Letters Patent No. 537,982, dated April 23,1895.

Application filed May 8, 1894. Serial No. 510,473. (No model.)

To @ZZ whom it may concern.:

Be it known that I, MILTON KEYS, a citizen of the United States, and aresident of Fort Vorth, in the county of Tarrant and State of Texas,yhave invented certain new and useful Improvements in Gearing forWindmills; and I do hereby declare that the following is a ful1,`clear,and exact description ofthe invention, whichk will enable others skilledinl after fully described and claimed.

In the accompanying drawings: Figure 1 is a sectional elevation of theupper portion of a windmill constructed in accordance with my invention.Fig. 2 is a similar sectional View taken at right angles to Fig. 1.

In the said drawings, the reference numeral 1 designates the uprights ofthe tower, which may be of any ordinary or suitable construction.Secured to the upper ends of these uprights or standardsis an annulus orring 2, provided with downwardly depending arms 3,

` bolted or otherwise secured to said uprights or standards. Seated androtatable upon this ring or annulus is a rotatable circular plate 4,having a downwardly depending annular liange 5 at its periphery, formedwith lugs 6, having inwardly projecting pins 7, carrying rollers 8 whichengage under said ring or annulus and hold the rotatable plate orturntable in place. The turntable or plate is also formed with a centraldownwardly depending iiange 5a concentric with iange 5 forming acircular recess in which is seated a metal ring 5b formed with a numberof downwardly depending bearings 5 in which are journaled rollers 5dwhich rest upon the upper side of ring 2. The turntable is supported bythe ring 5b and rollers. Secured to this plate are journal boxes 9, inwhich is journaled the power shaft 10, having at one end a windwheel notshown, which may be of any ordinary or suitable construction and at theother end provided with a friction-wheel 13, with which engages abrake-shoe carried by the vane 14. Also secured to said plate is abracket 15, formed with a hole 16 to receive the lower end of thevertical shaft 17, to which the vane 14 is attached. The upper end ofthis shaft is formed with a conical recess to receive the end of aset-screw 1S, passing through alug 19, formed with said bracket. Securedto said bracket and also to the plate 4, so as to rotate therewith, isaV housing 20, consisting of two plates 21, and a rim 22. Passingcentrally through this housing is the power shaft 10, having securedthereto a pinion 23, by which the pump rod is actuated.

The numeral 24 designates the pump rod, having at its upper end theconnecting rod 25, which in turn is pivotally connected with thevertically reciprocating slide 26. This slide consists of a metal platerecessed at its center forming a continuous bar 27, provided on itsinner side with cogs or teeth 28, with which said pinion engages. Theinner ends of this slide are provided with studs 29, having rollers 30,which engage in oblong cam slots 3l, ar-

ranged one above the other inthe same verti.

cal plane formed in the innerl side of one of the plates of the housing.The sides of each of these grooves are perpendicular and parallel witheach other, forming vertical ways conn nected together at top andbottom, by the curved ways. The said vertical ways of one slot arealigned with those of the other.

The operation will be readily understood. As the wind-wheel revolves itwill rotate the power shaft, which through the medium of the slide 26,and the cogs on the slide will reciprocateV the latter up and down andimpart a corresponding movement to the pump-rod which is connectedtherewith. The rollers 30 work in the slots or ways 3l, and guide theslide in its movement.

By this construction a steady, even, uniform movement is given to thepum p-rod, obviating many of the objections incident to the ordinarycrank-connection, thereby rendering the apparatus much more efficient inuse.

Having thus described my invention, what I claim is- In a windmill, thecombination with the ring or annulus 2, the rotatable circular plaie et,having a downwardly projecting annular ilange 5 at its periphery formedwith lugs 6 having inwardly projecting pins 7 carrying rollers S, whichengage under said ring or annulus, the downwardly depending annularflange 5, the ring 5l located between said flanges formed withdownwardly depending bearings 5c and the rollers 5d, loosely journaledin slots in said bearings, of the housing passing through and secured tosaid plate 4, the driving shaft passing through said housing andprovided with a pinion, the two oblong cam grooves formed on the innerside of said housing, one above the other, and Jthe sides of each ofsaid grooves being parallel and perpendicular, the verticallyreciprocating slide having rollers at top and bottom engaging with saidgrooves and formed with an oblong slot provided with rack teeth withwhich said pinion engages and the pump rod connected with said slide,substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

MILTON KEYS.
